Abstract (en)
[origin: EP0097419A1] A moulded polyethylene valve body (12) has a flow passage (18) connecting an inlet (20) with an outlet (22) of the valve body (12), a valve seat (24), formed integral with the valve body (12), surrounds the passage (18) and a plastics valve disc (26) is rotatably positioned in the passage (18) for movement into an out of sealing relation with the valve seat (24) to effect closing and opening of the passage (18) between the inlet (20) and outlet (22). A valve stem (28) is non-rotatably connected at one end to the valve disc (26) and extends through the valve body (12) and projects upwardly therefrom to an upper end portion. An actuator cap (72) is non-rotatably connected to the valve stem upper end portion. An external valve neck portion (120) surrounds the upper end portion of the valve stem (28) and is positioned on the outer surface of the valve body (12). The neck portion (120) is adapted to rotatably receive and support the actuator cap (72). A pair of clamp-like leg members (132,134) of the neck portion (120) extends circumferentially around the surface of the valve body (12) to connect the neck portion (120) to the valve body (12). Free end portions of the leg members (132,134) are brought under tension to maintain the leg members (132, 134) in gripping engagement with the valve body (12) so that the actuating forces from the actuator cap (72) are transmitted from the neck portion (120) and leg members (132, 134) uniformly around the surface of the valve body (12).
